Abstract:
Synthesis gas is a mixture of hydrogen and carbon monoxide, and can be used to obtain a great variety of products. Fischer-Tropsch Synthesis (FTS) is the most extensively used process for the synthesis of linear hydrocarbons from syngas. Lighter products can be used a diesel fuel, and heavier ones can be used as waxes. Higher Alcohols Synthesis (HAS) is a reaction process to obtain alcohols containing two or more carbon atoms. These alcohols can be used as intermediates for the synthesis of lubricants, detergents and cosmetics. The objective of this thesis is the study of CO hydrogenation using different types of supported catalysts to obtain fuel-range hydrocarbons via FTS, or to produce higher alcohols via HAS. The first block of the thesis studies the effect of zeolite acidity and mesoporosity in FeCuMgK catalysts supported on ZSM-40 and ZSM-240. The second block evaluates the influence of metal loading on binary and ternary FeCoCu catalysts supported on mesoporous silica SBA-15 for the production of higher alcohols.
